To all inkom z'tmzy concern Be it. known that Lf LLOYD N; BnoWN, a citizenr o'llA United States, residing at Charlotte, in 'the county of Aecklenburg and State of-North Carolinmhave invented ce1'- tain new andyuseful Improvements rin RoofingL'I'iles, of which the followingis a specification.

rlhis inventionlrelatyes to roofing tiles and has, as its to provide a roofing tile which may` be readily and cheaply molded from cement or other plastic material and which whenlemployed in the construction of a roof; will prove durable and water-proof and' will possess numerous other advantages rendering? it a desirable substitute for boards; `shinglesrand metal in roof' structures.

Qne object of the invention is to so constructy the tile that a number offtiles may be readily and conveniently laidl upon any skeleton; roof structure' embodying rafters or s iniilajr timbers suitably spaced, and in such manner tlliat after the tiles have been laid theywill presenta smooth upper surface to Whipha coating 'of tar or any other suitable materia-l may applied either over the en tire' facesV of that-iles or along he seams between thet'les, so as to render the roof absolutely `waterproof;v l

.Mnpther object ofthe invention is to provide a tile o'the'class In'1entini'ec-l with a reinforcing rnezms which willserve also as a Ihas whereby" thetile I'nay be anchored `to rafters f of the'seleton rooff structure' so as to 7lief'sef'zu'rely1v 'heidi against' displeenent in any direction. j

A i nther object ofi the inventionr is so the-'nite that in the con''pletedV roei menare every une win be tethered te or Connected* wiftlf the tile vor at eitheror botlhisides' thereof? so 'that the roof structure winl be "Substantially integral tiiniiigliut. l 'y Thel invention has as a; further 'objectfto renee a, tile 0f 'this'elassgwitheeppbinng aegee-g n., its oppesite laterali edg'eefwiiiegi @e with tteaaugeser adje ce tiges @enana-nary meeting aegee edge wenn upper efifge'oatns rafterthe seid latere; edges 'bf thermes beneath `naar sind constituting shoulders which abut hefotiposing' `-farces of the rafters so an te neeraaiiy' provide a" jj inst Minardi plmeieemfehy Leef lAnother object of the invention is tn provide a. tile constructedI as above brieiypointr ed out, with reinforcing wires embedded tendin reinforcing elements which serve not on to strengthen the tile but which are also so ocated within the tile andwith relation to the end portions of the wires rstinentioned as to effeetjlally prevent these wires bein torn' through the under-side of the tile wien the Wires have their ends brought together and twisted in the manner above stated.

In the aGeomI Janyingll drawings:

Given a gni-1eme aan@ peana-,1w bf th ne een an* pre-emanan@ distance, the tiles for conipleting the roof structure will bel of a width between their lateral edges substantially equal to the distance between the said rafters so that when the tiles are arranged upon and betweenv the rafters, their lateral edges will abut again-st the opposing faces of adjacent rafters in the manner clearly shown in Fig. 2- of the drawings. In order that the tiles may be supported when so laid, each lateral edge of the tile is formed with a projecting flange 2 which is of a thickness substantially equal to one-half of the thickness of the body of the tile and which, therefore, occupies the upper half of the respective lateral edge of thetile as shown in the said figure. The flanges furthermore are of a width substantially equal to one-half of the thickness of the rafters of the skeleton roof structure so that when the tiles are laid in the manner shown in the said Fig. 2, the flanges of adjacent tiles will substantially meet edge to edge and the underfaces of the flanges will rest upon the upper edges of the rafters. In order that the meeting ends of adjacent tiles may be joined so as to render the roof substantiallywater-proof or leak-proof even without the application of any coating thereto, as heretofore referred to, one end edge of each tile, which is to constitute the lower edge if the roof is inclined, is formed with a flange 3 extending the entire width of the said end of the tile and constitutingr in effect a right-angular continuation of the flanges 2, being of the same thickness as the said flanges and occupying the same plane. The other end edge of each tile is formed with a rabbet 4 proportioned to receive the flange 3, as clearly Shown in Fig. 3 of the drawings. When the tiles are molded of proper dimensions and the roof structure has been properly built, the tilesv when laid will so meet or join one another that the roofstructure will .be substantially water-proof or leakpr0of,-but it will, of course, be usually deslrable to apply; a coating oftar or other suitable material along the seams between the tiles so as' to fill or ,close the said seams, Of course, where the roof is to have a conformation other than flat, the bodies of the tiles will be molded. accordingly and therefore the. present invention is not limited to the fiat side tile shown in the drawings-but the drawings on the other hand are to be taken merely as illustrative ofthe principles of the invention. 1 y

As before stated, combined` reinforcing and tie wires Iare molded in the body of the tile and thesewires are indicated in general by the numeral 5 andl in preparing each tile, two of the` wires have theirintermediate portlons twisted'to ether as indicated by the l numeral 6, the sai intertwisted intermediate portions extending at lthe longitudinal middle of the body ofthe tile. lying substanti-ally midway between the upper and under faces of the tile. Beyond their twisted intermediate portions,the wires are led either directly or indirectly laterally to points adjacent the corners of the tile as indicated by the numeral 7 and are thence trained downwardly substantially vat right angles as indicated by the numeral 8, so that the ends of the wires will extend Athrough and beyond the under-face of the tile. Of course, as there are two of the wires 5 in each tile, there will be four ends projecting beyond the said-under-face of the tile, one located adjacent each corner of the'tile. The projecting ends of the wires are of such lengths that when the tiles are laid upon` the rafters in the manner shown in Figs. 2 and.

3 of the drawings, the corresponding ends of the wires of laterally adjacent tiles may 'be brought together beneath the intervening rafter and twisted as indicated by the numeral 9 and clearly shown in Figs. 2 and 3 of the drawings. Of course, when the ends of the wires are twisted together the projecting end portions will be. tensioned so as to firmly draw the flanges 2 down on to the upper edges of the rafters and the tiles will in this manner be firmly bound or anchored lin place and prevented .from being displaced in any direction. Y

In order-to elfectually anchor the portions 7 of the wires 5 in the'tile and prevent the wires being torn through the under side of the tile when their ends are twisted Atogether beneath the rafters 10, vreinforcing bars or rods 11 are embedded inthe tiles and these bars or rods are preferably corrugated throughout their lengths. The bars .or rods l1 are so located that their ends will extend beneath the portions 7 of the wires 5;.one of the bars 11 being located adjacent each end of the tile body and extending. transversely thereoff In this manner theawires 5 are eifectuallyprevented from@ being pulled throughfthe tiles and additional reinforcement is given the tile. f

If deslred or found necessary, a stripev 12 of heavy vcloth material, carpet or in fact.- any yieldable material may be laid or secured upon the upper edge of each rafter, as shown in Fig. .4 of the drawings so as to compensate 'forI expansion and contraction.

Having thus described the invention, what is claimed.- as new is:

l. A roofing., tile comprising a cementitions body, relnforcing elements embedded transversely therein near the ends thereof, and wires embedded-in the body and .having their middle portions intel-twisted and :dis-
